Abstract :
For the data fusion of integrated navigation system, the different data-updating rate of each navigation subsystem will cause the loss of information and introduce the new error source. Therefore the data synchronization of all navigation subsystems should be carried out before effective data fusion. In this paper, the data synchronization technique of INS/GNSS/TAN integrated navigation system is investigated in time and space level respectively. And the synchronization algorithm based on analytical extrapolation and position transformation is proposed. The practical applications validate that this synchronization algorithm is effective.
